chore: switch to algoliasearch v5 (#1410)

Pins dependencies used from the swizzled `SearchPage` component. The
undeclared dependencies were causing the documentation build to fail in
the dependent packages (e.g.
[here](https://github.com/apify/apify-cli/actions/runs/12755096920/job/35550383965)).

Removes the unused `@apify/docsearch-apify-docs` package from the
dependencies.
